PCYT2 inhibits epithelial-mesenchymal transition in colorectal cancer by elevating YAP1 phosphorylation.

ABSTRACT: Metabolic reprogramming is a common feature in tumor progression and metastasis. Like proteins, lipids can transduce signals through lipid-protein interactions. During tumor initiation and metastasis, dysregulation of the Hippo pathway plays a critical role. Specifically, the inhibition of YAP1 phosphorylation leads to the relocation of YAP1 to the nucleus to activate transcription of genes involved in metastasis. Although recent studies reveal the involvement of phosphatidylethanolamine (PE) synthesis enzyme phosphoethanolamine cytidylyltransferase 2 (PCYT2) in tumor chemoresistance, the effect of PCYT2 on tumor metastasis remains elusive. Here, we show that PCYT2 was significantly downregulated in metastatic colorectal cancer (CRC) and acted as a tumor metastasis suppressor. Mechanistica
